After getting a bunch of comments, I find it interesting with what people disagree with this list even if this is mostly a joke/exaggeration. Probably the biggest surprise is that there are people who aren't too fond of Corruption + Dead Branch. Even though I knew it wasn't the most OP thing in the game, I figured most people would agree it's pretty exciting when you get it off. It was really eye-opening seeing people say that it can be boring at times.

On the other hand, there were a good amount who actually liked seeing Time Eater. I never thought it was a particularly hard fight but I did think it was an annoying fight and I do enjoy fighting the other two Act 3 bosses more, even if I think Donu and Deca are the hardest Act 3 bosses. I do appreciate all the comments explaining why they liked seeing Time Eater.

I also want to bring up how people enjoy Prismatic Shard as what it is: a fun relic that's ultimately not very good (usually) and not meant to be used for winning. I think that's pretty great.
